I picked up one of these real cheap without it's cabinet and I never realized how big there are and there power.
This amp is 28 inches wide and outputs a combined 275 watts RMS from two separate output stages.
I can't wait to get it working right!

Need Help. My fuse blew in amp. Changed worked fine then one day cut on heard loud buzz opened up inspected and had dc volts on output speaker +-7v got a schematic found that most caps where swollen leaking resistors where chipped and off by a mile. Changed everything blew fuses again PC 5131 rev 0. Even changed out IC Se504L to C504H. In rectifier CR4-CR7 are the same part number but originally two on one side where white, with a red stripe going down the side. Idk what they were. Can't find any info on them. Think I now have damaged pads from reworking. Going to try and re do with a perf board. If anyone knows anything about mystery diodes. Or maybe just a alternative Power amplifier I could drop in instead I would appreciate the help and info.
